Thank you!

I think this is a great course with a lot of content and is a good place to start. Thank you for preparing this course.

I liked how you explained it in an easy-to-understand way.

I found this lecture because I was interested in studying data engineering, and the explanation was very helpful and easy to understand. I was able to learn a lot while building a big data cluster on AWS. Thank you~

I think this is the most suitable lecture for those who are building a cluster for the first time. Don't be afraid of the theory part at first, and if you don't understand it, you can understand it sufficiently in the code lab and increase your understanding of the system. It was good that I could build a cluster so easily while proceeding quickly and concisely. At this point, a 404 page appears when downloading and installing the package, but you can install it by going to the site and matching the appropriate version. I personally think it would be better if you updated it. I want to try attaching more diverse engines, loading data collected from outside, and visualizing it. I would be so grateful if you could create an additional lecture that connects Impala and Airflow to the built system!

I'm disappointed with the difficulty of the lecture!

I am taking this course because I am interested in building and analyzing big data systems. I liked that the theory and practice were conducted together!

I listened carefully. It was very helpful for my work.

I am listening carefully to the necessary technologies for using big data. It is one of the difficult fields, but thanks to the good explanation, my understanding of the cluster environment has improved. I think it is different from other lectures because there is a part about building. I am also taking the pipeline class, and I am really grateful that you introduce various technologies and explain them well so that I can use them right away. Thanks to you, I am interested in AWS, create storage, and create EC2 to receive the necessary resources for free. Thank you~

It's good to master what's practical and necessary.
